DISCHARGING AND MACHINING METHOD AND DEVICE USING DISCHARGING PULSE

摘要

PROBLEM TO BE SOLVED: To provide a discharging and machining technique capable of stably forming micro concave parts by discharging marks without manually adjusting a tool electrode even when the tool electrode is worn.SOLUTION: In relatively moving a tool electrode 16, the tool electrode 16 is rotated to cause a swinging movement or a turning movement due to a centrifugal force. While the tip 16a of the tool electrode 16 is rotated around a workpiece 2, a discharging pulse is applied between the workpiece 2 and the tool electrode 16 at a predetermined interval.
